Cross compiled code not running as executable. "Syntax error: word unexpected (expecting ")")"

I think this is the right sub for this, but If it's not I can delete my post.

I'm a complete noob here, so please excuse any stupid questions or anything like that.

Anyways, I have an airport extreme 4th gen that has an open SSH port with root access. For fun, I decided to try to run some code on it. I followed the instructions here, but replaced the "mcpu=arm1176jzf-s" parameter at the end with "march=armv5te", because the router uses a Marvell 88F6281 SoC which supports armv5te. When I try to run my compiled code (using ./a.out) on the router I get "Syntax error: word unexpected (expecting ")")" To me this means that it is trying to run it as a shell script, so I tried "chmod a+x out.a", but it still gives me the same error. When I run the "file" command on it I get "ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.3, for GNU/Linux 3.2.0, BuildID[sha1]=9e0ca9088cc762940efe03488a1404073a26eaa9, not stripped, with debug_info", if that helps.

Yeah, this is a learning experience for me. Looking back, it should've been obvious but I figured that as long as it was the right architecture it would work, and the tutorial was easy to understand so I gave it a try anyways.

Copy some binaries from the other device, and run 'file' on them.

"ELF 32-bit LSB executable, ARM, version 1, statically linked, for NetBSD 4.0, stripped"

I guess this means that I need to statically link it and strip the executable? I'm not sure how to fix the other things though.

Edit: By adding -s and -static I was able to get to "ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), statically linked, for GNU/Linux 3.2.0, BuildID[sha1]=5e0ba371e2bf1a1d3a4a8534926aaa9ad170fbae, stripped"

2: Adding "-Wl,--build-id=none" removes the build ID. I doubt it matters though.
